Noise when barking (low speeds)

Hi all, when I brake at very slow speeds (say, when parking slowly or when approaching a speed bump) I sometimes get a noise that comes from the front. Not sure if a noise coming from the brakes or the suspensión. This will happen both when going straight or with the wheel turned. Haven´t heard it when braking at speed.

Has anybody had this issue? Would it have to do with break-in from some of the parts?

you don't mention the type of noise? Grinding? Clunking ?

Grinding can sometimes be caused by dirt between the pad and the disc (hard material like a bit of metal). Check on your discs for any lines forming, that will be a give-away.

Clunking could be more serious. If you drive at a constant speed and lightly touch the pedal do you hear it ? Does it happen every time or only sometimes? If it's every time could be a loose caliper (I've not examined the V40 brakes so not sure exactly what to tell you to look for) / the housing of the assembly could be loose / loose bolt somewhere.

If it's really concerning, take it back to the dealer, let them take a look. You don't mention the age of your vehicle but I am guessing it's fairly new. It is probably under warranty and most dealers would happily let a mechanic take 5 minutes to listen to a potential safety issue without charging you.

Thanks for your answer.

Hard to describe the noise. I guess the best way to describe it, would be like a humming noise. Does not happen every time, and when it happens, it´s when I lightly touch the brake pedal but only at slow speeds (or at least haven´t heard it at higher speeds maybe due to road noise). It is a new car, only 730 kilometers on it. I guess safest thing would be to get the dealer look at it, but wanted to check if anyone else has encountered that issue.

Take it to the dealer, may be something to do with the servo ABS etc. it does not sound mechanical anyway (which would be easier to solve)

I have the same problem, particularly in reverse parking. Very low pitched noise at very low speed. It's been to Volvo workshop five times already and it seems that they take apart the callipers, regrease them and a day or two later the same noise re-appears. I'm now at my wits end and its seems that Volvo technicians are also clueless as to what's causing this problem. Ironically, my brakes had to be replaced at 30000KM at the car was hardly a year old (brand new). Initially when I bought the car, there was noise when braking but more a high pitched dust noise (or that's what we thought).
